Clarification on thread direction for saw arbors please

Post by jtp »

theres a lot of contradictory info out there as far as thread direction on SS saw arbors, is it reverse/left handed thread for all of these arbors?

The answer is simple. With the nut loose, if you hold the nut and rotate the arbor in the normal direction, does the nut tighten.

So if the nut is on the quill side as in the top pix, the threads need to be left handed. If the nut is on the other side(AWAY FROM THE QUILL) the threads need to be right handed. If a tongued washer is between the nut and the blade, it does not matter.

One arbor in your pix is a 5/8" arbor, those are RH thread. It is on the one that looks like a plywood blade with 180 tooth on the label. (The nut is on the other side, as JPG described.)
